About Meter

The meter is the SI base unit of length, defined using the speed of light. It is the foundation for centimeters, millimeters, and kilometers.

About Nanometer

The nanometer is one billionth of a meter. It describes wavelengths of light, semiconductor features, and molecular scales.

How to convert meters to nanometers

1 meter is equal to 1.00000000e+9 nanometer:

1 m = (1 m ÷ 1e-9 m) nm = 1.00000000e+9 nm

Each meter is defined as 1 m and each nanometer as 1e-9 m, so one m equals 1 ÷ 1e-9 nm = 1.00000000e+9 nm.

Let d(m) be the numeric value of the same length measured in Meter (m), and d(nm) the value in Nanometer (nm). Then:

d(nm) = d(m) × (1 / 1e-9)

Equivalently, divide by how many m fit into one nm (meters per nm divided by meters per m):

d(nm) = d(m) ÷ 1.00000000e-9

Or: nanometer = meter ÷ 1.00000000e-9

Examples

Example #1: Convert 20 m to nanometer

20 m = 20 m × (1/1e-9) nm = 20000000000 nm

20 m = 20 m ÷ 1.00000000e-9 = 20000000000 nm

Example #2: Convert 50 m to nanometer

50 m = 50 m × (1/1e-9) nm = 50000000000 nm

50 m = 50 m ÷ 1.00000000e-9 = 50000000000 nm

Summary

To convert Meter to Nanometer, multiply the value in m by the ratio of meters per m divided by meters per nm. Equivalently: value_nm = value_m × (1 / 1e-9). Numerically, 1 m equals 999999999.9999999 nm.

Relationship context

Both units are metric (SI) and tied to the meter. Converting between them uses powers of ten (or simple rational factors), so the relationship is exact in decimal arithmetic. The factor from Meter to Nanometer is 1.000000e+9 (1 m = 999999999.9999999 nm).
